4 inch PVC DWV 90 Degree Elbow Plastic x Plastic

4 inch PVC 90° Elbow – Standard Fitting for DWV Systems

The 4 inch PVC 90° Elbow is designed for use in gravity-fed drain, waste, and vent (DWV) piping systems. It provides a 90-degree change in direction and is suitable for installations where a short-radius transition is acceptable per applicable code requirements.

Manufactured from rigid polyvinyl chloride (PVC), this fitting offers structural reliability, corrosion resistance, and ease of joining with solvent weld connections. It is intended for use in non-pressurized systems and conforms to dimensional standards established for DWV fittings in residential and commercial construction.

• ✅ Standard Radius Bend – Facilitates tight directional changes where space constraints or layout geometry require a compact turn.
• ✅ Solvent Weld Socket Ends – Accepts 4 inch Schedule 40 DWV pipe for permanent, leak-resistant joint connections.
• ✅ Non-Metallic Durability – Resistant to scaling, rust, and a wide range of chemical agents commonly encountered in drainage environments.

Technical Specifications

• Material: Schedule 40 PVC (Polyvinyl Chloride)
• Nominal Size: 4 inches
• Connection Type: Socket x Socket
• Angle: 90 degrees
• Application: Drainage, Waste, and Ventilation (DWV) systems
• Standards: Conforms to ASTM D2665 and D3311

Installation requires use of PVC primer and solvent cement in accordance with local plumbing codes. Proper pipe insertion depth and alignment are critical to achieving a sound joint. This fitting is commonly used in vertical-to-horizontal transitions and at cleanout access points where standard 90° turns are permitted.

Typical Use Cases

Used in both residential and commercial DWV systems for above-ground or underground installation, including wall cavity runs, mainline offsets, fixture drains, and stack offsets.

Material Properties

Schedule 40 PVC exhibits excellent resistance to acids, alkalis, and bacterial growth. Its smooth bore surface minimizes friction losses and helps prevent buildup of solids in waste systems.

The 4 inch PVC 90° Elbow offers a code-compliant, cost-effective solution for DWV installations requiring a right-angle transition. Its standard radius form factor is widely accepted across construction disciplines and supports long-term performance in sanitary applications.
